It is possible that Republican Senate nominee Rand Paul never saw what happened.
A woman wearing a wig -- who would later identify herself as Lauren Valle -- attempted to approach him as he got out of his SUV to attend the final Kentucky Senate debate with Democrat John Conway.
She was wrestled to the ground by Rand Paul supporters. After she was on the ground, one man wearing a Rand Paul shirt and stickers put a foot on her shoulder and stomped.
Valle later appeared to be unharmed. She said she represented "Republicorp," a fictitious company which is the brainchild of MoveOn.org. She claimed that Republicorp was the merger between the Republican Party and corporate America.
She said she was in Kentucky to present Rand Paul with the employee of the month award. The sign she carried supported her claim.
A spokesman for Rand Paul said,"Violence of any kind has no place in our civil discourse and we urge supporters on all sides to be civil to one another as tensions rise heading toward this very important election."
